As the mobile phone revolution brings video, photos and Web pages to
our handsets, telecommunications experts from around the globe have
been collaborating to develop standards to underpin third-generation
phone systems. This book is an in-depth assessment of WCDMA (Wideband
Code Division Multiple Access), the main third-generation air
interface. WCDMA will be deployed in Europe and Asia at the same
frequency band, (around 2GigaHerz) and it is expected to spawn a whole
host of new gadgets. It will allow mobile phone companies to launch an
array of new services. The authors all work for Nokia, one of the
companies leading the move to wideband communications, and as might be
expected, this is a comprehensive assessment of the technology. <br>It
explains how WCDMA differs from today's digital interfaces, its main
features, the background to it becoming a global standard, and gives
valuable advice on getting the best performance from 3G networks. It
also examines other technologies which could be used to provide
multimedia phone services, such as EDGE, the evolution of GSM for high
data rates. <br> <br>WCDMA for UMTS: Radio Access for Third
Generation Mobile Communications is aimed at technology and
communications students, technical people working for device
manufacturers and service providers and frequency regulators. It
includes a comprehensive glossary and lots of diagrams which should
make it an invaluable desk reference for anyone working in the rapidly
evolving telecoms world. --Shan Ni Ceallaigh --This text refers to an

Mobile wireless systems have become the ubiquitous means of mass
telecommunications over the past 15 years. The early 'first
generation', analogue systems were optimised for voice communications
only but the proliferation of differing standards, particularly within
Europe led to the development of a common digital based approach. The
resulting 'second generation' system, GSM, now dominates the world
mobile market; however this system, too, was designed and optimised
primarily for voice services, albeit with the option for low speed data
over the voice channel. Over recent years, the growth in demand for
access to Internet based multi-media enabled mobile telecommunications
system. <br> <br> <br> What is now emerging, globally, is a range of
proposals under the generic title IMT2000 for a terrestrial system
based on five radio interfaces standards and three core network
technologies - all of which should provide for full inter-working of
services and applications in all continents! <br> <br> <br> Next
generation mobile wireless clearly embrace a wide range of technical
disciplines and are influenced in no small part by the underlying
commercial and political aspirations of the many parties world-wide
committed to its successful implementation. Indeed it so difficult for
any individual to remain expert in all the necessary areas. <br> <br> <br>
Within Europe the adopted approach is know as UMTS. A new radio
interface based on WCDMA (Wide Band Code Division Multiple Access) is
currently in the final stages of standardisation for a first release
(r'99) and the initial UMTS system will be based on a GSM core network
as enhanced to support the soon to be publicly launched GPRS packet
data system. <br> <br> <br> The standardisation work for UMTS is
being carried out under the auspices of 3GPP, the 3rd Generation
Partnership Project and the editors and chapter contributors of this
new book, all of whom are with Nokia, are to be congratulated on
providing a detailed description of the WCDMA air interface and its
utilisation and in providing a set of references to the appropriate
3GPP Technical Specifications. <br> <br> <br> Chapter 1 introduces
the third generation air interfaces, the spectrum allocation, the time
schedule, and the main differences from second-generation air
interfaces. Chapter 2 presents example UMTS applications, concept
phones, and the quality of service classes. Chapter 3 introduces the
principles of the WCDMA air interface, including spreading, the Rake
receiver, power control, and handover. Chapter 4 presents the
background to WCDMA, the global harmonisation process, and the
standardisation. Chapters 5-7 give a detailed presentation of the WCDMA
standard, while chapters 8-11 cover the utilisation of the standard and
its performance. <br> <br> <br> Chapter 5 describes the architecture
of the radio access network, interfaces within the radio access network
between base stations and radio network controllers and the interface
between the radio access network and the core network. Chapter 6 covers
the physical layer (layer 1), including spreading, modulation, user
data and signalling transmission diversity and handover measurements. <br> <br> <br>
Chapter 7 introduces the radio interface protocols, comprising the data
link layer (layer 2), and the network layer (layer 3). Chapter 8
presents the guidelines for radio network dimensioning, gives an
example of detailed capacity and coverage planning and addresses GSM
co-planning. Chapter 9 covers the radio resource management algorithms
that guarantee the efficient utilisation of the air interface resources
and the quality of service; these algorithms are for power control,
handover, admission and load control. <br> <br> <br> Chapter 10
presents packet access in WCDMA and includes the results of dynamic
system simulations. Chapter 11 analyses the capacity and coverage of
the WCDMA interface at rates up to 2 Mbps. Chapter 12 introduces the
time division duplex (TDD) mode of the WCDMA air interface and its
differences from the frequency division mode (FDD). A brief overview of
the characteristics of multi-carrier CDMA, one of the alternative air
interfaces proposed IMT2000 is given in chapter 13. <br> <br> <br>
Whilst not a book for the novice, the WCDMA for UMTS does achieve its
objective in presenting a detailed description of the FDD operating
mode. The TDD mode, which in the opinion of this review will have a
very significant part to play in the future of UMTS, particularly given
the asymmetric nature of multi-media traffic and the unpaired spectrum
allocations available both now and likely as extension bands for UMTS,
does not receive all the attention it deserves and, inevitably, the
standardisation activities have moved on in both this area and that for
packet access since the book was published. And for those seeking an
overview of the complete UMTS system, the text does not address the
core network for UMTS. <br> <br> <br> That said, this is the first
book published to describe the UMTS air interface and I would certainly
recommend it as the starting point for anyone seeking a way in to the
3GPP Technical Publications. --This text refers to an out of print or
